The Waterbird Society has published results of scientific research for over two decades beginning with a proceedings of papers presented at the annual meetings from 1978 to 1980 followed in 1981 by a refereed, international journal, formerly called Colonial Waterbirds. In 1999, the journal became Waterbirds to reflect the society's expanded focus on all aquatic birds and their habitats. The journal is produced by an editor and an international panel of associate editors and is open to submitted papers concerning the biology, conservation, and techniques of study of the world's waterbirds including seabirds, wading birds, shorebirds, and waterfowl.

The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

Least Bittern (Ixobrychus exilis) occupancy surveys were conducted in the Arkansas Delta, USA, during April-July 2005-2006 to determine the proportion of area occupied and relate occupancy to habitat characteristics. Previous large-scale surveys indicated few Least Bitterns were present in the Delta. During surveys at 190 sites, Least Bitterns were detected at 15 sites in 2005 and at 16 sites in 2006. Several candidate models were tested to explain occupancy based on habitat variables. Emergent vegetation cover was positively related to occupancy while the proportion of forest within 400 m of a survey site was negatively related to occupancy. The study suggests that managing the breeding habitat of Least Bitterns for emergent vegetation cover and controlling forest cover near occupied sites may contribute to this species' recovery throughout its range.
